The part is ultrasonically melted to form the mounting fixture 16 on the bracket 20, and the bracket 20 is disposed between the mounting fixture 16 and the door trim body 1.
, The bracket 20 is fixed to the door trim main body 1.

At the time of this ultrasonic welding, the horn 2
Of the horn 2 protrudes, and the outer periphery of the horn 2 hits the bracket 20 and emits a resonance sound, giving the operator a feeling of pain.

The mounting boss is inserted into the mounting hole of the mounting component and then melted to form a mounting fixing portion of the mounting component to the automobile interior component. It is characterized by being formed so as to extend to the outer periphery of the mounting component together with the mounting component.

中の共鳴音の発生を防止できる。According to the present invention, since the fixing part for fixing the mounting part to the interior part of the vehicle is formed on the mounting part and extends to the outer periphery of the mounting part, the interior part for the automobile is formed. Since the mounting boss is made of the same material as the parts, if the mounting boss melts and reaches the interior parts for automobiles, it is compatible with each other, so it is integrated with the interior parts for automobiles. As a result, it is possible to prevent rattling of the mounting parts and prevent the ultrasonic welding horn from coming into contact with the mounting parts, thereby preventing generation of resonance noise during work.
